Well I can't pronounce it or spell it. The new bullets from agulalia? I shot the 60 grn'rs out of my Rem 541-T, and they all key holed, even at 10 ft! they suck in my book. I bought some of the 20 grn'rs with no powder, just primer powered, they shoot ok in either my Rem 541-T or my Win 67. They knock a tin can around a bunch without puttin a hole in it! Drops fast but fun. VERY quiet, It sounds like your dry firing, and rolling a BB down the barrel. I still say a BB gun is cheaper!
